The best setup in my view is test pipes or an x-pipe with HFC. Pairing either of these with OEM muffler or even the OEM-perforated pipe cover method. Those are the two only ways to completely 100 percent eliminate drone, keep the high pitch raspy race sound and keep the 20whp gain all with no drone.
